Specialized Crux 5 Comp SRAM Rival XPLR

The Fastest Gravel Race Bike Specialized Has Ever Made

The Specialized Crux 5 Comp SRAM Rival XPLR is engineered for riders who want maximum speed, efficiency and control across gravel roads, rough tracks and race courses. Combining an ultra-lightweight FACT 10r carbon frame with cutting-edge SRAM Rival AXS XPLR wireless technology, the Crux 5 Comp transforms every watt of effort into forward momentum. Designed around real-world gravel racing performance, it delivers exceptional climbing ability, precise handling and impressive capability on demanding terrain.

At the heart of the bike is Specialized's FACT 10r carbon frame, weighing just 897 grams and developed using the same innovative design principles that made the Aethos one of the lightest bikes ever produced. The result is a gravel bike that accelerates quickly, climbs effortlessly and remains comfortable over long distances. Rider-First Engineered™ technology ensures every frame size delivers the same balanced ride quality and performance characteristics.

The SRAM Rival AXS XPLR 13-speed groupset provides crisp wireless shifting and an impressive gear range thanks to its 10-46T cassette and dedicated gravel-specific drivetrain. Hydraulic disc brakes offer powerful, consistent stopping performance in all weather conditions, giving riders confidence when descending steep gravel roads or navigating technical sections.

Specialized has also designed the Crux 5 Comp to be incredibly capable. With clearance for tyres up to 55mm (2.2"), riders can tailor their setup for everything from fast gravel racing to rugged adventure riding. Combined with progressive gravel geometry and the lightweight S-Works FACT carbon fork, the bike delivers outstanding stability, traction and control without sacrificing speed.

Rolling on durable DT G540 wheels and equipped with Specialized's gravel-focused finishing kit, the Crux 5 Comp is ready for racing, bikepacking adventures or epic weekend rides straight out of the box. Whether you're chasing podiums or exploring new roads, this is a gravel bike built to go further and faster.
